NOSE SHIELD Filed Sept Patented Apr. 21, 1931 DANIEL. H. ROCHE, OFPAWHUSKA, OKLAHOMA NOSE SHIELD Application filed September 22, 1927.Serial No. 221,316.

My invention relates to new and useful improvements in a nose shieldandresplrator and has for its principal object'the provision of such adevice which may be readily positioned on the nose or removed therefrom,said shield including wings which carry a gauze or other suitablematerial through which the air drawn into the nostrils may be filteredand such wings being adapted for swinging movement so that they may beproperly positioned over the openings of the nose or left spaced fromthe openings.

Another object of my invention resides in the provision of members whichwill engage the partition and walls of the vnose to hold the shield inproper position, the wall en-- gaging members having extensions whichare adapted to engage the upper lip of the'wearer and thereby aid insupporting the shield.

A further object consists in forming the wings of hinged sections whichmay be opened, or separated, for positioning the gauze or other materialtherein it being appreciated that because of the accumulation of dirt orother matter, or because of being worn, it will be desired to change thesaid gauze or materials at intervals.

With the above and other objects in view, which will appear as thedescription proceeds, my invention consists in the novel details ofconstruction, and arrangement of parts, described in the followingspecification and illustrated in the accompanying drawings, and while Ihave illustrated and described the preferred embodiments of theinvention, as they now appear to me, it will be understood that suchchanges may be made as will fall within the scope of the appendedclaims.

In the drawings Fig. 1 is a rear view showing my shield in position tobe attached to the nose.

Fig. 2 is a section on the line 2-2 of Fig.- 1

looking in the direction of the arrows.

Fig. 3 is a detail perspective of one of the wings.

Fig. 4 is a transverse section on the line H of Fig. 3; and v Fig. 5 isa perspective of one of the wings showing the sections thereof inseparated position.

In the drawings 1 indicates a substantially U-shaped' frame preferablyformedfroin a strip of resilient metal whichmay be bent into the desiredshape. Theends of the strip forming the frame are made to provide thesubstantially vertically extending eye portions 2 and intermediate thetop and bottom of the frame the strip is made to form the 0 inwardlyextending arms 3 having the substantially horizontally extending eyes 4formed at the inner ends thereof. As quite clearly illustrated in Fig. 1of the drawings the inner ends of the arms 3 are spaced adistanceapartso as to receive the partition walls of the nosethcr-ebetween. The frame being resilient may be sprung sutficiently toallow the partition wall of the nose to pass between the inner ends ofthe arms and when released the arms will engage on opposite sides ofthepartition wall. The lower portion of the frame will extend below thelower or outer edge of the nose partition.

Extending through the eyes 2 are the rods 5, said rods being of such adiamter as to snuggly fit the interior of the eyes and adapted to beheld therein by friction. The lower ends of the rods are bent in themanner as more particularly illustrated in Fig. 2 of the drawings toform the portions '6 and 7 with the diagonally extending arm 8 formed onthe end of the portion 7. The arms 8 of the rods are adapted to receivethe wings to be later described. The rods 5 may be adjustedlongitudinally in the eyes 2, and as previously stated, held in suchadjusted positions by friction.

The wings which are rotatably and slidably mounted upon the arms 8, ofthe rods 5, comprise the frame portions 9 and 10 which are pivotallyconnect-ed by means of the hinge 11. The frame 9 is provided with theelongated eye portion 12 t irough which the arm 8 is adapted to pass andthe eye of such a diameter as to frictionally engage the arm andnormally hold the wiagainst sliding or rotatable movement. It will. beunderstood that the friction may be overcome, when desired, to adjustthe wings. The frames 9 and 10 are normally held together, or in closedposition, by means of the pivoted latch shown at 13 carried by the frame10. This latch is adapted to be swu g to engage over the ends of theframe shown more particularly in Figs. 1, 2 and 3 of the drawings. Agauze or other suitable filtering material 14 is clamped between thesections 9 and 10 of the frame and has an extension 15 which is foldedto extend over the outer face of the Wing as shown more particularly inFig. 4 of the drawings. The two layers of the gauze or other fabric areheld in spaced relation by means of a pin 16, one end of the pinextending through the gauze clamped between the frames of the wing andthe other end of the pin extendingthror ":1 the folded extension 15. Themanner in i.

-iich the pin 16 is used is quite clearly illustrated in Fig. 4 of thedrawings and adjacent each end of the pin is an enlargement 17 whichlimits the distance which the ends of the pins may pass through thefabric. The fabric carried by one of the wings of greater length thanthat carried by the other wing to provide the extension 18 as shown moreparticularly in Figs. 1 and 2 of the drawings, and adapted to be usedfor a purpose and in a manner to be later described. lVhen it is desiredto remove or replace the gauze or other filtering material the pivotedcatch 13 is swung into the position shown more particularly in Fig. 5 ofthe drawings and the fran'ie portions of the wing may be swung on thehinge to sepa rate the frame portions and allow the material to beremoved and replaced The frame 10 has the concaved extension whichengages the outer face of the sleeve 12.

Extending through the eyes 4- 0f the arms 3, and frictionally heldtherein, are the rods 20 having their outer ends bent to form the arms21 and the extensions 22. The arms, as quite clearly shown in Fig. 1 ofthe drawings, extend outwardly in opposite directions to engage theinner surfaces of the walls of the nose. The extensions 22 are adaptedto engage the upper lip of the wearer to aid in holding the shield inposition on the nose. From the above detailed description it is thoughtthat the construction of my shield will be readily understood and I willnow endeavor to more clearly bring out the manner of using. My shield isadapted to be attached to the nose and the wings ca 'rying the gauze orother filtering material are adapted to be swung into position over thenose openings. When applying the shield the rods 20 will be rotateduntil the arms 21 are directed downwardly. The arms 21 are then graspedand the shield positioned on the nose. The frame will be inserted intothe nose until the lower portion of the frame engages the end of thenose partition and the ends of the arms 3 will en 'age on o n ositesides of the nose partition. It will be understood that the upper endsof the rods 5 and the sleeves 2 will. be positioned within the nosebetween the outer walls thereof and the partition. hen the frame is inposition the rods 20 are again rotated to bring the outer ends of thearms 21 into engagement with the outer walls of the nose with theextensions 22 resting upon the upper lip adjacent the nose. The shieldwill be thus readily supported upon the nose. lVhen in the position justdescribed it is necessary to swing or adjust the wings so that thefiltering material such as gauze will cover the nose openings. It willbe seen that the rods 5 are adapted for sliding or rotatable movement inthe eyes 2 and that the wings are adapted for both sliding and rotatablemovement on the arms 8. Therefore proper adjustment may be secured sothat the wings may be swung to cover the nose openings. The extension18, of the filtering material, carried by one of the wings may be drawnbeneath the nose partition and en gaged over the end of the pin 23carried. by the opposite wing. By doing this a complete closure of theend of the nose is accomplished and as one breathes the air entering thenose will be filtered or cleansed. It will be noted that each of thewings has a double thickness of the filtering or cleansing material andthat the thicknesses are separated by the pins 16. As one breathes thecleansing material will vibrate. The shield may be removed by swingingthe wings away from the nose and by grasping the extensions 22 the rods20 are rotated to remove the extensions 21 from engagement with thewalls of the nose. The frame can then be withdrawn from the nose.

A shield such as I have described and illustrated is of advantage inpreventing the entrance of impurities into the nose and. may be worn bythe travelers in trains or motor vehicles, by engineers or firemen, bythose who suffer from hay fever or the like to prevent pollens fromentering the nose, or in fact by any one who desires to prevent theentrance of dust or other impurities into the nose. By having theseveral parts adjustable. as has been described, the shield is adaptedfor use under various conditions and thriltcring material may be changedwhen des .d

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is 1. A nose shield comprising a frame adaptedto engage the partition of the nose, and

filtering members carried by the frame and adjustable relative theretofor positioning over the nose openings, said filtering members includingeach a frame and filtering material carried thereby, the filteringmaterial carried by one of the frames having an extension adapted toextend beneath the nose partition and to be engaged with the oppositeframe.
